...Gustavo Lopes; Sergio Lavagnoli This work investigates the unsteady interactions between incoming wakes and purge flow in a high-speed low-pressure turbine cascade tested under engine-representative conditions. Experiments were conducted in a linear cascade at outlet Mach and Reynolds numbers...

.... The linear cascade counts 23 blades with a span of 165 mm. More details about the turbine cascade geometry can be found in Ref. [ 20 ]. The experiments were carried out in the closed-loop high-speed, low-Reynolds number wind tunnel S-1/C located at the von Karman Institute. This facility allows...
